Long after it opened, services were planned in the north-west section of the M25, near Chalfont St Peter.

Very little is known about the original plan. It picked up the baton after the rejected options at Colnbrook and Iver. It became known as the Warren Farm debate, which eventually led to a public inquiry in which Beaconsfield and Cobham were chosen to be built instead.

There would have been services on either side of the busy motorway.

New Plans

In August 2017, Highways England started building a new exit on the M25 south of J17, which is to allow construction vehicles direct access to the High Speed 2 railway construction site. They claim the sliproads (which are very well-aligned) will only have 10 years service. In October 2018, Extra announced that they wanted to use this site in future to build a large service station, very similar to Cobham.

A public meeting was planned for 23 October 2018, but it turned out the meeting was by invitation only and primarily for discussing how to raise awareness of the proposal.

Kings Langley Plan

In 2016 there were reports that Moto had been investigating the possibility of a service area in this area. This appeared to go away in favour of other planned sites, but they later revealed that they would be pursuing proposals for a service area and hotel at M25 J20, Kings Langley. This will be positioned off a new roundabout on the busy A41, with the building raised above the height of the road to offer an uninterrupted view across the valley.

In October 2018, as Extra's plans came into the public eye, Moto launched a mini-site for Kings Langley services. An official planning application was made in April 2019. Moto said they ruled out the Extra J17-J18 site because it's too small and too dependent on HS2. They also looked at building at either side of J17 and to the north of J20; all apparently too constrained.

The Kings Langley site is 9.02 hectares in size, and Moto say it will create 200 full-time jobs. The slope which the main building will be built on is artificial, as it's mostly made up of spoil from the M25 widening works in 2012. Using this slope means the delivery yard can be underneath the building. The lodge and petrol station will have grass roofs.

Space has been allocated for Greggs, Arlo's, M&S Simply Food, WHSmith, Costa, KFC, Burger King and a gaming arcade, as well as the usual petrol station, motel and drive-thru coffee shop. The motel, whose franchise hasn't yet been decided, will be a three-storey building set into the hillside, with 80 rooms.

Although Moto have called it Kings Langley services throughout the public planning process, they have suggested some stakeholders are pressing for it to open as Watford services.
